NB-IoT
NB-IoT (Narrowband Internet of Things) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular IoT devices and services. It operates in licensed spectrum bands, offering extended coverage, deep indoor penetration, and long battery life for massive-scale IoT deployments. It is designed to connect a large number of low-throughput, low-cost devices with minimal power consumption.
Developers should learn NB-IoT when building IoT applications that require long-range connectivity, deep indoor coverage, and multi-year battery life, such as smart meters, asset tracking, environmental monitoring, and agricultural sensors. It is particularly useful in scenarios where devices transmit small amounts of data infrequently and need reliable, secure connectivity over cellular networks without the complexity of traditional mobile broadband.
